This is not a bug, it is by desing.

If you create exactly one symbol (an alias, variable or a function) and it
matches the template name, you can access it without fully qualified name, like
this:

template foo()
{
    const int foo = 42;
}

const int f = foo();

but if you introduce a second symbol then you should fully specify it:

template foo()
{
    void foo() {}
    int bar(int i) { return i; }
}

foo!().foo();
int bar = foo!().bar(42);
